EYELET.

SPECIFICATION forming part of Letters Patent No. 554,624, dated February11 1896.

Application filed November 13, 1895. Serial No. 568,822. (No model.)

T0 at whom, it may concern:

Be it known that I, ELEAZER KEMPSHALL, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Eyelets, of which the following is aspecification.

This invention relates to a new and improved eyelet; and .it consists inthe novel features of construction and relative arrangement of partshereinafter fully described in the specification, clearly illustrated inthe drawings, and particularly pointed out in the claims.

Reference is to be had to the accompanying sheet of drawings, forming apart of this application, in which like characters indicate like partswherever they occur.

In the drawings, Figure 1 represents a perspective view showing aneyelet constructed in accordance with my invention. Fig. 2 represents alongitudinal sectional view thereof.

a represents a tubular-shaped body formed at one end with an overhangingflange a, that is concavo-convex in cross-section. The free andoverhanging edge of this flange is formed with spurs a that extendtoward the end of the member arnot provided with a flange. (Here shownas extending downward.) The shape and number of the spurs or projectionsare immaterial, and their purpose is to rest upon the die-plate b inorder that the plastic material, which forms the covering for theflange, maybe forced through the spaces between said spurs to fill upthe concave under side of the flange, further permitting the material inthe spaces to firmly anchor the plastic material upon the outside to theplastic material that fills up the concave under side.

It will be apparent that if the lower edge of the flange were notprotected with projections the edge of the flange of the eyelet-blankwould be forced down against the die-plate and none of the plasticmaterial would enter the concave under side. Moreover, supposing theconcave under side to be filled with plastic material, unless there werecommunications between the material upon the inside and outside in orderto bind the two layers together, there would be the liability of one orboth being broken from the blank, either by use or by expansion.

1) represents the covering of plastic material, which is molded aboutthe top flange a by a suitable shaped die, and made to fill the space inthe concave under side of the flange. The ends of the spurs ct, restingupon the dieplate, will be exposed in the completedarticle, as isevident, while the spaces between the spurs a will be filled withplastic material, firmly binding the covering upon the blank. The diewill be so shaped as to confine the plastic material upon the inside ofthe eyelet, substantially as shown, in order to give the completedarticle a finished appearance,

the covering of plastic material forming a continuation of the innerwall of the member a.

Having thus explained the nature of my invention and described a way ofconstructing and using the same, though without attempting to setforthall of the forms in which it may be made or all the modes of its use,what I claim, and desire to secure by Letters Patent, is-

1. An eyelet comprising in its construction a tubular-shaped body, anoverturned flange, forming an extension of said body, said flange beingconcavo-convex in cross-section, and spurs upon the free andrearwardly-extending .edge of said flange, substantially as and for thepurpose set forth.

2. An eyelet comprising in its construction a tubular-shaped body, anoverturned flange, forming an extension of said body, said flange beingconcavo-convex in cross-section, and spurs upon the free andrearwardly-extending edge of said flange, adapted to rest on a dieplate,and a covering of plastic material molded about the top of said flange,and filling the concave under side thereof, the plastic material uponthe top and bottom sides of said flange being united in the spacesbetween said spurs, substantially as and for the purpose set forth.
